Definitions

  • ⁇ O )Q N are capable of affecting plant growth.
  • the anhydro compound is a 6-oxo-2-phenyl-4,5benzo- 1,3-oxazi-ne.
  • Agents according .to this invention which contain one of the said compounds as active substance are contact herbicides which have a selective herbicidal action in crops, particularly when used in post-emergence methods. They are particularly valuable by reason of the rapid commencement of action and the fact that they have no after-effects.
  • the agents according to this invention are advantageously used in admixture with solid or liquid carrier substances with the addition of emulsifiers, dispersing agents or wetting agents in the conventional way for plant protecting agents.
  • suitable liquid carriers are water, mineral oil fractions, diesel oils, coal tar oils, cyclic hydrocarbons, and solvents, for example alcohols, ketones, aliphatic hydrocarbons or chlorinated hydrocarbons.
  • suitable solid carriers are chalk, bentonite, diatomaceous earth, bleaching earths, talc, calcium carbonate, boric acid, calcium phosphate, sawdust or cork powder.
  • the various forms of application may be better adapted to the various uses in the conventional Way by adding substances which improve distribution, adhesion, resistance to rain and penetrating power, for example fatty acids, resins, Wetting agents, emulsifying agents, glue or alginates.
  • substances which improve distribution, adhesion, resistance to rain and penetrating power for example fatty acids, resins, Wetting agents, emulsifying agents, glue or alginates.
  • the biological activity spectrum may be broadened by adding substances having bactericidal, fungicidal or plant growth inhibiting properties, for example substituted phenoxycarboxylic acids, acid anilides, chlorinated fatty acid esters or trisu'bstituted ureas.
  • Improvement in the action of the agents is also achieved by adding borates, chlorates, thiocyanates, primary phosphates, methyl arsonates and cacodylic acid.
  • Example 1 2.5 kg. of anhydro-(N benzoylanthranilic .acid) suspended in 500' liters of water is sprayed on each 2 hectares of the following plants in a greenhouse: Hordeum vulgare (barley), Avena sativa (oats), T riticum sativum (wheat), Secale cereale (rye), Sinapis alba (mustard), Urtica wens (small nettle), Matricaria chamomilla (wild camomile) and Galium aparine (cleavers). The plants are about 5 cm. in height.
  • Benzoylanthranilic acid has a similar action to anhydro- (N-benzoylanthranilic acid).
  • Example 2 pletely withered, while maize and rice have not been damaged.
